Honda is adding 1.39 million more airbag inflators as part of the ever-expanding Takata airbag recall.

The company said the National Highway Traffic Safety Administration, after reviewing Takata’s revised estimate of 34 million defective inflators, told Honda to increase its earlier May recall expansion of 350,000 cars. The new recall is for passenger-side airbags on 2003–2007 Accord and 2001–2005 Civic models—two vehicles with the highest defect rates uncovered in Takata tests. This latest expansion brings Honda’s U.S. total to 6.28 million cars, including Acura.

Honda has been at the bull’s-eye of the Takata airbag recall. Last Friday, Honda confirmed the seventh death from a Takata airbag in one of its vehicles—all of the recorded deaths have been in Hondas—and last week took the unusual step of amending its 2014 annual report to include $363 million incurred from airbag repairs. The company has been recalling defective Takata airbags since 2008.

The replacement inflators, half of which are produced by Takata’s competitors, may take years to reach the market and also may be just as defective, according to a recent Congressional hearing. For full, updated recall information on Honda and every affected automaker, visit our Takata page.

UPDATE 6/16, 12:00 pm: The total number of airbag inflators subject to this new recall has been updated, as has the total number of Honda vehicles affected by Takata-related recalls.
